Abstract

Disclosed herein are vehicle accident recorders and methods for generating accident information thereof. A method may include receiving an accident message transmitted from an accident vehicle; confirming a distance between a vehicle and an accident point and whether or not a view confirming the accident point is secured, based on accident data included in the accident message; and generating witness data for the accident point depending on results of the confirming of the distance between the vehicle and the accident point and whether or not the view is secured.

First claim

What is claimed is:

1. A method for generating accident information of an vehicle accident recorder, the method comprising:
receiving, with a communicator of the vehicle accident recorder, an accident message transmitted from an accident vehicle;
confirming, with a controller of the vehicle accident recorder, a distance between a vehicle and an accident point, based on accident data included in the accident message;
confirming, with the controller, whether a view of the accident point is secured, based on the distance between the vehicle and the accident point;
confirming, with the controller, whether the vehicle is able to acquire image data of the accident point based on an altitude difference between the accident vehicle and the vehicle included in the accident message; and
generating, with the controller, witness data for the accident point depending on confirmation of whether the view of the accident point is secured and confirmation of whether the vehicle is able to acquire image data of the accident point.

2. The method according to claim 1 , wherein the accident data includes an accident time and an accident position.

3. The method according to claim 2 , wherein the accident data further includes a movement direction of the accident vehicle and crash information of the accident vehicle.

4. The method according to claim 3 , wherein the accident data further includes a request distance of the witness data, altitude, a recent driving trajectory, speed immediately before an accident, and position accuracy.

5. The method according to claim 1 , wherein confirming the distance between the vehicle and the accident point comprises:
confirming a position of the accident point by parsing the accident message;
processing distance data between the accident point and the vehicle;
confirming whether the distance data is not more than a reference distance; and
when the distance data is not more than the reference distance, confirming the view of the accident point is secured.

6. The method according to claim 5 , wherein the distance data is processed using a Harversine operation.

7. The method according to claim 5 , wherein processing the distance data comprises processing a request distance of the witness data included in the accident data and the distance data by reflecting satellite accuracy.

8. The method according to claim 5 , wherein confirming whether the view of the accident point is secured includes,
confirming whether the accident vehicle and the vehicle are positioned on the same road;
processing an altitude difference of the accident vehicle and the vehicle;
when the accident vehicle and the vehicle are positioned on the same road, confirming whether the vehicle obtains image data of the accident point; and
when the image data of the accident point is obtained, generating the witness data.

9. The method according to claim 8 , wherein confirming whether the accident vehicle and the vehicle are positioned on the same road includes,
operating the altitude difference of the accident vehicle and the vehicle; and
confirming whether the altitude difference is less than tolerance.

10. The method according to claim 8 , wherein in confirming whether the image data of the accident point is obtained,
a driving path, a movement direction and steering angle information of the vehicle are pieced together to confirm whether the accident point is positioned within a view range of the vehicle.

11. The method according to claim 8 , wherein the witness data includes a data acquisition time, a data acquisition position, a movement direction of a data acquisition vehicle, and image data.

12. The method according to claim 11 , wherein the witness data further includes speed and an image device specification of the data acquisition vehicle.

13. A vehicle accident recorder comprising:
a communicator configured to receive an accident message broadcasted from an accident vehicle;
a vehicle information collector configured to collect vehicle data; and
a controller configured to:
confirm a distance between a vehicle and an accident point, based on accident data included in the accident message received through the communicator;
confirm whether a view is secured based on the distance between the vehicle and the accident point;
confirm whether the vehicle is able to acquire image data of the accident point based on an altitude difference between the accident vehicle and the vehicle included in the accident message; and
generate witness data for the accident point depending on confirmation of whether the view of the accident point is secured and confirmation of whether the vehicle is able to acquire image data of the accident point.

14. The vehicle accident recorder according to claim 13 , wherein the controller is configured to process distance data between the accident point and the vehicle based on the accident data and configured to confirm whether the vehicle is positioned within a reference distance from the accident point.

15. The vehicle accident recorder according to claim 14 , wherein the controller is configured to reflect satellite accuracy at the time of processing the distance data.

16. The vehicle accident recorder according to claim 13 , wherein the controller is configured to process an altitude difference of the accident point and the vehicle and configured to confirm whether the accident point and the vehicle are positioned on the same road based on the altitude difference.

17. The vehicle accident recorder according to claim 16 , wherein when the accident point and the vehicle are positioned on the same road, the controller is configured to confirm whether the vehicle obtains image data of the accident point.

18. The vehicle accident recorder according to claim 17 , wherein the controller is configured to piece together a driving path, a movement direction, and steering angle information of the vehicle and configured to confirm whether the accident point is positioned within a view range of the vehicle.
